python 2.7 - Use of a dictionary + Bitarray -

-

i need know if bitarray in dictionary not why code not work, idea?

    dic={}     bb=bitarray()     bb.append(false)      temp=bitarray()     temp.append(false)     dic[bb]=""      if temp in dic:         print("hello")

this tricky one. dict's keys should hashable. said, let's take @ hashes generated both bitarrays. 

>>> bb bitarray('0') >>> temp bitarray('0') >>> hash(bb) 1871851 >>> hash(temp) 1871843

therefore, when attempt if temp in dic:, hash of temp not found in dic. therefore don't desired result. don't know why hash of bb , temp different.

you instead:

>>> dic[bb.tostring()] = 'test' >>> if temp.tostring() in dic: ...     print 'hello' ... hello

you use bb.tobytes() dict's key if desire. in case, use temp.tobytes() comparison.
